Introduction
UNESCO works to advance and promote science in the interests of peace, sustainable development and human security and well-being, in close collaboration with its Member States and a wide variety of partners. It is the only United Nations specialized agency, symbolized by the ‘S’ in the acronym, with a specific mandate for science. Since its foundation in 1945 UNESCO has acted as a catalyst for the establishment of many, now leading, scientific unions and bodies such as CERN; and initiatives with far-reaching implications for sustainable human security and well-being, such as the Man and the Biosphere Programme, the International Hydrological Programme, and the Intergovernmental Oceanographic Commission, were launched in UNESCO’s first decades.
